Let's divide 70159661 by 398
Let's see how many times 398 fits into 70159661.

Going ahead to step 1:
The number 398 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 398

Going ahead to step 2:
70 divided by 398 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Fetch the next digit (1) from the dividend, attach it to 70 and continue: 701 / 398

Step 3:
When dividing 701 by 398, we get 1 with a remainder of 303.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 398 away from 701, we end up with 303.
Bring next digit (5) of the dividend behind the 303 and repeat the process: 3035 / 398

Let's proceed to step 4:
398 goes into 3035 7 times with a remainder of 249.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 2786 away from 3035, we end up with 249.
Include the next digit (9) from the dividend after 249, then repeat: 2499 / 398

Going ahead to step 5:
If we divide 2499 by 398, we get 6 and a remainder of 111.
The next digit of our result is 6. 
Result so far: 176.0
The remainder is 111 after subtracting 2388 from 2499.
Append the next digit (6) from the dividend to 111 and continue with: 1116 / 398

On to step 6:
1116 divided by 398 is 2 with a remainder of 320.
The next digit of our result is 2. 
Result so far: 1762.0
The remainder is 320 after subtracting 796 from 1116.
Fetch the next digit (6) from the dividend, attach it to 320 and continue: 3206 / 398

Moving on to step 7:
The number 398 fits into 3206 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 17628.0
Subtract 3184 from 3206 to get 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 398

Let's proceed to step 8:
398 can be fit into 221 0 times, resulting in a remainder of 221.
Record the quotient 0 as the next digit in the result. 
Result so far: 176280.0
Deduct 0 from 221 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 9:
When dividing 2210 by 398, we get 5 with a remainder of 220.
The next digit of our result is 5. 
Result so far: 176280.5
Subtracting 1990 from 2210 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 10:
2200 divided by 398 is 5 with a remainder of 210.
The next digit of our result is 5. 
Result so far: 176280.55
Subtract 1990 from 2200 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 176280.55, with a leftover of 0.21.
